"The mission was completed in a record time of 4 years 2 months and the spacecraft was tested in a very short span of 18 months. We expected it to have a lifespan of 6 months. It has already completed 100 days of existence in the Mars orbit and is expected to last at least 6 more months."

Quote
"It would be too early to speak about the findings of the mission. But the data being received from the craft is of very good quality. Scientists find it to be very useful while analysing it," Radhakrishnan said replying to a question.

Quote
The ground team was able to manoeuvre the craft to save it from a possible encounter with a comet, he said. The 'auto' mode of the mission too has been tested. Scientists are now waiting for June, when the craft would be out of reach of the ground control for around 15 days.

"If we could regain control over the craft after that period, that would be one more major achievement," Radhakrishnan said.

The Indian Space Research Organisation (Isro) is likely to make an announcement regarding extended life in the coming days. However, how much longer MOM will live will be known only after a solar eclipse in April-May.

An Isro official told TOI last week that MOM's fuel consumption has been minimal.

Confirming this on Saturday, a senior scientist said: "As we speak, only about a kilogram of the 40 kg fuel it had after insertion into the Martian Orbit has been used up. So yes, MOM will live longer."

Quote
"As of now, MOM is being maintained by ground stations. We have control over how much fuel to expend, whether a manoeuvre is required or not and other specifics. But during the eclipse, MOM will get into an autonomous mode and we will have no control over it," a senior official said.

Explaining that solar panels on MOM currently power a lot of sub-systems and fuel is only being used for small auto-corrections, he said: "During the eclipse, MOM may expend fuel to turn the panels to position it towards the Sun, or even use some for repositioning itself in the orbit and so on; we really cannot guess how much fuel it may use."

These slides were presented by an American scientist with permission of the Indian MOM team at the recent NASA MEPAG meeting in California. The scientist visited India in late January. I'm going to summarize his remarks (some of them very interesting) in a separate post.

Richard Zurek of JPL presented the above slides on the Indian MOM mission at the MEPAG meeting yesterday. Zurek had recently traveled to India to meet with them about their mission and also to invite them to speak to MEPAG. The Indians declined because a) their planetary science community is very small, and b) they could not afford the time when they are so focused on their mission. They gave him those slides and granted permission for him to use them.

Zurek said that following about his meeting:

-The Indians are very happy with how their spacecraft is currently performing. They are not experiencing any problems. They now expect MOM to last for the rest of 2015. It may make it into 2016 as well, although they would not project that far.
-MOM's only consumable is fuel and their fuel usage is good.
-They are now focusing on the Chandrayaan-2 lunar mission. Because their community is so small they cannot work on more than one mission at a time. C2 is likely to slip into 2018 or later.
-They have plans for a MOM-2 mission. Although they would like to do it for the 2018 window, they indicated that was highly unlikely, so it will probably be 2020 at the earliest.
-MOM-1 was a technology demonstrator. They were clear that MOM-2 will be a science mission.
-Nothing has been defined about MOM-2 other than it will use a larger launch vehicle.
-They are not very interested in extensive cooperation with the United States. Zurek said that this is primarily (he thinks) because they view themselves in competition with China, so cooperating with the United States doesn't have the benefits that beating the Chinese does.
-There is the possibility of the U.S. and India exchanging instruments on future spacecraft (like happened on C1), but that is likely the extent of the cooperation.

That was generally it.

Orbiter records the Red Planet’s albedo

 The Methane Sensor for Mars (MSM) on board the Orbiter recorded the albedo (fraction of solar energy
reflected from the surface of celestial bodies back into space) of Mars while attempting to measure the
reflectance in 1.65 micron, ISRO said in its post on a social networking site.
A senior ISRO official told The Hindu , “This is the first time the measurement of albedo is being
recorded in the reflectance level of 1.65 micron. The data recorded would be studied and it can also
help in finding out whether methane is present in Mars.”
The column density of methane, if available, would also be measured.
“Reflected solar radiation from Mars is a diagnostic signal of the planet which provides lot of
information about the planet’s surface as well as its atmosphere. When we measure the radiance in a
specific wavelength of light (in 1.65 micron), then we can generate a reflectance map,” the post said
and has shared the map generated with data collected till December 16 last year.

Methane Sensor for Mars (MSM) payload onboard MOM intends to detect the presence of Methane and measure the column density of the same. One of the secondary objectives of this payload is to measure the reflectance of Martian surface in 1.65 micron. MSM has two channels, Methane and reference to measure the radiance from the surface of Mars.
All planets in the Solar system receive Sun’s radiation to varying degrees depending on their distance from the Sun. Observing the surface of the planet depends on how this radiation is reflected back. Reflected solar radiation from Mars is a diagnostic signal of the planet which provides lot of information about the planet’s surface as well as its atmosphere. When we measure the radiance in a specific wavelength of light (in this case, 1.65 micron), then we can generate a reflectance map.
The map presented here shows the surface reflectance of Mars as viewed at 1.65 micron from the reference channel of MSM till December 16, 2014. In the map, the blue colour indicates low albedo features and the red shows high albedo features on the Martian surface.
The map resolution is 0.5°x0.5° in Latitude-Longitude. By correcting the data for CO2 absorption, a major part of atmospheric effects is taken care of. This data along with the reflectance measured by Mars Colour Camera will be useful to study the surface properties of Mars.

http://www.hindustantimes.com/india-news/mangalyaan-mission-ends-on-march-24-but-spacecraft-to-remain-operational-after-deadline/article1-1326985.aspx

Quote
Mangalyaan — the country's first spacecraft to Mars — will complete its six-month mission next week on March 24, but will remain operational even after its assignment duration expires.

Indian Space Research Organisation (Isro) chairman Dr Kiran Kumar told HT the mission would technically end next week. "The satellite will remain operational even after that as there is no fuel constraint. This will help us delve deeper into the seasons and climate on Mars. We have been able to capture some beautiful images of Mars and have got ample data. Analysis of the data is being done and once this is final, it will be made public," Kumar said.

Quote
The Isro chief said a lot would depend on the blackout period for Mars in June. "The next challenge for the spacecraft will be in June next year when all three - Mars, Earth and Sun-will be in one line.  There will be no communication (blackout period) with the spacecraft for nearly 14 days."

The blackout would be experienced between June 8 and 22 as the Sun would come between Earth and Mars. During the blackout period, the spacecraft would be in fully autonomous mode and no data would be transmitted to or from it.

Pital Crater - Picture from Mars Color Camera (MCC) on 23-04-2015

Pital crater is an impact crater located in Ophir Planum region of Mars, which is located in the eastern part of Valles Marineris region. This  image is taken by Mars Color Camera (MCC) on 23-04-2015 at a spatial resolution of  ~42 m from an altitude of 808 km.

Wall of the crater and chain of small impact craters are clearly seen in this image. This crater is having the diameter of ~40 km.

 Most of craters observed on planetary surfaces are circular in shape. Some of the craters are in elliptical shape.  However, this Pital crater is in different shape.  This could be due to the eastern extension of regional fracture in the W-E trending fracture zone.

MOM heads for a 2-week blackout

Quote
India’s Mars Orbiter Mission will be in the communication blackout phase between June 8 and 22 when there will be no communication between MOM and the ground stations.

The Rs 450-crore MOM has been moving into the blackout phase since May 27 and transmitting only three hours of data every day. Between June 8 and 22, the sun will come between earth and Mars causing a complete communication blackout.

An Isro official told TOI that MOM has already been configured for the challenging phase and was currently in “safe mode”, wherein some of the payloads have been deactivated.
This will be the first time since its launch on November 5, 2013, that MOM will be completely autonomous.

Right now MOM has a reserve capacity of about 37kg of fuel, which is a comfortable situation. However, during the two-week blackout phase, we will not know how much fuel it will consume while executing manoeuvres. We will be able to assess its mission life only after doing an analysis after the blackout ends, especially with regards to availability of fuel,” the Isro official said.

Simulations relating to the blackout have indicated that there was no cause for anxiety. MOM has so far transmitted about 200 images. Data from the other four payloads are being analyzed.

"From June 8 to 22, the sun will block Mars from the earth snapping communication with the satellite.

MOM during this period will go into an "autonomous mode" and will take its decisions, a senior Indian Space Research Organisation official told PTI.

"This will be for the first time that there will be a communication break for such a long period of about 15 days. During this period, there will not be any communication with the satellite," he said.

Expressing confidence about regaining control over the satellite once the blackout phase is over, he said, "the scenario has been tested for earlier; line of communication will be established."

Mars Orbiter Spacecraft under ‘solar conjunction’ at Mars

Mars Orbiter Spacecraft (MOM) is under ‘solar conjunction’ at Mars, which means the spacecraft, which is orbiting Mars, is behind the Sun as viewed from the Earth.  As a result of this event which happens once in 2.2 years for Mars, communication signals from the spacecraft are severely disrupted by the Sun’s corona (outer atmosphere).  The reason for this is the charged particles from the sun and they are responsible for the reception of noisy signals at the ground antenna from the spacecraft .

The conjunction for Mars Orbiter Spacecraft began on May 27, 2015 and will extend up to July 01, 2015.  No commands are transmitted to the spacecraft during this period for safety reasons and only telemetry (spacecraft’s health related information) is monitored..  All payload (spacecraft’s scientific instruments) operations are also suspended.  Health of the spacecraft is normal.
